HATER-FRONT FOE FIRE-POTS OF FURNACES.

Specification of Letters Patent.

Patented Oct. 21, 1913.

Application filed July 3, 1 912. erial No. 707,539.

To all whom it may concern:

Be it known that I, BENJAMIN H. VAN AUKEN, a citizen of the UnitedStates, residing at Syracuse, in the county of Onondaga and State of NewYork, have invented certain new and useful Improvements in ater-Frontsfor Fire-Pots of Furnaces; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new-and useful improvements in water heatersfor hot air furnaces and the object in view is to produce a fire pothaving an offset or recess formed in the wall thereof for the receptionof a water-containing tank and having communication with circulatingpipes, the walls of the tank being preferably corrugated to allow forexpansion and contraction of the metal thereof. 7

The invention comprises various other details of construction andarrangements of parts which will be hereinafter fully described, shownin the accompanying drawings and then specifically defined in theappended claim.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a portion of a fire pot, a portion ofthe same and the tank and recess containing the latter being shown invertical section. Fig. 2 is a top plan view of the fire pot and tank,and Fig. 3' is a detail in elevation of the tank showing inlet and exitopenings therefor.

Reference now being had to the details of the drawings by letter, A andA designate two sections of a fire pot, one superimposed upon the otherin the manner shown and adapted to be cemented together. Said sec tion Ais provided with an ofiset B, forming a recess or pocket, the oppositewalls of which are grooved as at D, and E is a water tank E, preferablynear its bottom and at one end thereof, and through which pipe wateris'adapted to pass to the tank. An exit opening N leads from the tanknear its top and through which the heated water may pass and be piped,if desired, to any suitable location. I

By the provision of a device as shown and described, it will be notedthat a simple and efiicient hot water circulating system is afiorded forready attachment to ordinary hot air furnaces, utilizing the direct heatfrom the fire pot and affording additional heating system cooperatingwith the heat of radiation from the hot air furnace. In the event of itbeing desired to replace the tank, it may be done by simplydisco-nnecting the pipes which pass through the wall of the fire potand, by removing the top off the fire pot, the tank may be re leasedfrom its offset.

hat I claim to be new is In combination with the'fire pot of a furnacehaving a recess formed in the wall thereof, the opposite wall of therecess having vertical grooves, a receptacle conforming to and adaptedto fit within said recess and having ribs at the ends thereof engagingthe grooves in the end walls of the recess, the inner surface only ofthe receptacle being directly exposed to the heat within the fire pot,as set forth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
